Trifluoromethylated nucleic acid analogues capable of self-assembly through hydrophobic interactions
0022-2836/$ see front matter © 2008 E The initial events in protein aggregation involve fluctuations that populate monomer conformations, which lead to oligomerization and fibril assembly. The highly populated structures, driven by a balance between hydrophobic and electrostatic interactions in the protease-resistant wild-type Aβ21–30 peptide and mutants E22Q (Dutch), D23N (Iowa), and K28N, are...
The adsorption of a collagen fragment on both a hydrophobic, hydrogen-terminated and a hydrophilic, natively oxidised Si surface is investigated using all-atom molecular dynamics. While favourable direct protein-surface interactions via localised contact points characterise adhesion to the hydrophilic surface, evenly spread surface/molecule contacts and stabilisation of the helical structure oc...
The peculiar nature of temperature-induced vesicle aggregation (TIVA) in some catanionic surfactant systems is systematically investigated. On the basis of a general analysis of the intervesicular interactions, the main driving force for this phenomenon is considered to be the intervesicular hydrophobic interaction among the exposed hydrophobic part of the surfactant headgroups. The addition of...
Based on the mutational effects on the steady-state kinetics of the electron transfer reaction and our NMR analysis of the interaction site (Sakamoto, K., Kamiya, M., Imai, M., Shinzawa-Itoh, K., Uchida, T., Kawano, K., Yoshikawa, S., and Ishimori, K. (2011) Proc. Natl. Acad. Sci. U.S.A. 108, 12271-12276), we determined the structure of the electron transfer complex between cytochrome c (Cyt c)...
We have synthesized model hydrophobic silicone thin films on gold surfaces by a two-step covalent grafting procedure. An amino-functionalized gold surface reacts with monoepoxy-terminated polydimethylsiloxane (PDMS) via a click reaction, resulting in a covalently attached nanoscale thin film of PDMS, and the click chemistry synthesis route provides great selectivity, reproducibility, and stabil...
